How To Choose The Right Sized Grinder
Larger Jobs, Bigger Grinder
When talking about a grinder’s size, this is usually measured by the disc part of the machine and not the overall length or size. Of course, the handle gets consequently bigger to better control the disc as it increases in size. But disc size is the primary factor of a grinder’s size.
An angle grinder’s most common size for homeowners is 4.5 inches, which is the measurement of the disc’s diameter. That’s because it’s the most efficient for the few odd woodwork jobs around the home. For larger jobs that require very long or deep cuts the size of the device will drastically increase.
There are limits for practical and safety reasons, but most jobs and DIY projects will not require industrial size machinery.
Big Wheels, Deep Cuts
If you need to cut thick and strong materials like concrete and stone, you’ll need a machine that has a bigger disc size. Even if a smaller grinder manages to cut through your material, you’re going to spend a long time with your project.
If you get a tool with a bigger wheel, the project can be done is less time and with more ease. If you’re dealing with wood as a material, most of the grinder sizes can manage the task. It’s just a matter of thickness in choosing the right size for your project.
Small Grinder, Faster Spin
It’s all a matter of simple physics, really. The smaller the disc, the faster it finishes one whole spin. 4.5 inch grinders can reach speeds of over 11,000 RPM. With this speed, these small devices can accomplish the tasks of cutting and polishing metal.
However, with great power come great setbacks. Smaller grinders are more susceptible to overheating as compared to their larger siblings. It’s highly recommended to get one with customizable speed settings so as not to keep on using the highest setting all the time. Even though bigger models operate at a lower speed, they are less likely to overheat and thus will perform better.
There is, however, a little detail that you should note. The amp rating of the motor also plays a large role in the speed that a grinder can spin. Just to be sure how exactly your grinder is expected to perform, check the RPM rating. This is a lot more reliable.
Grinders For Newbies
If you’re new to such tools, it’s best to note the power that they possess. It’s made of metallic discs that are sharp and heavy duty. You can easily see where it might pose a danger to you, especially if you’ve never handled one before.
f you’re going to be using a grinder for the first time, the best advice is to start small, and always wear protective gear like a face plate and gloves (for better handling, since the grinder vibrates a lot).
Don’t get a bigger grinder and attempt to use it for the first time because you’re still not used to handling one. 7 inch grinders cannot be operated by one hand, so imagine just how things could quickly get out of control.
Practice with a small one first to be able to get used to the feeling of how it reacts and handles, then move on to the bigger leagues when you’re ready.
Cordless Angle Grinder
The larger your grinder is, the more power it will require to work. So, it’s not uncommon to see large grinders with high powered motors of 110 or 240 volts. This makes them pretty bulky, and nothing is more inconvenient than trying to reach into a tight workspace only to find out that the cord of your grinder is not long enough.
It’s bad enough maneuvering the bulky tool in the first place. So if you see that this is a likely scenario in your near future, you might want to get a smaller model. These can operate on a mere 18 volts and often use a rechargeable battery for power. A lot of these will work at full power for quite some time, so they’re quite convenient to use.
Important Decision Factors
Before you just pick a model and get start, you should be aware of a few things. If you make a conscious decision on these you can avoid disappointment. And you will not end up with a tool that gathers dust at the back of a box.
Value For Money
Value, in this sense, refers to the amount of use that you could get out of the machine that you buy. That usually depends on the extent of work that you’re going to need it for. For home improvement purposes, a 4.5 inch disc can usually get the job done. The general rule is the more specs, the more value you can get from it.
However, this does not mean that you should get the tool that has the most specs, unless you’re going to find a use for all of those features. It’s like buying a full kitchen appliance set when you only need a refrigerator: it’s a waste of money if you’re not going to be utilizing all or most of it. Quantity matters, but quality is just as relevant.
Dust ejection system. Spindle lock. Paddle switch. What are these specs that can often be seen on standard marketing material? These are the safety features, and you must keep these in consideration when choosing an angle grinder.
Safety has a twofold meaning here: keeping you safe from harm, and protecting your investment with a tool that lasts longer. Find the best angle grinder that has features to help keep you from getting exposed to injury like an adjustable guard.
A “dead man switch” is also necessary. If you think that the grinder is posing danger to you and to itself you can ensure it cuts out immediately. As a result, you also don’t accidentally turn on the grinder and end up with a serious injury because of a simple mistake. Despite the presence of these safety features, it’s still best to wear the proper protective gear when using an angle grinder.
Make and Model
In searching for the right angle grinder, you will see that there are brands that have already established their name in the power tool world. You’ll most likely come across DeWalt, Makita, Bosh and Hitachi, all of which are pretty good and trustworthy brands.
Still, it’s going to be tricky choosing the best out of all of them, as some may have the best quality while the other may offer the best deal. And yet another one has the best features. It’s all a matter of determining which one really fits your needs at the moment.
We’ve already established this in the first part of this article: you will have to choose the specs of the disc based on what you’re going to use it for. Less abrasive discs are great for polishing, while more abrasive ones are perfect for cutting and grinding even the toughest materials.
At the end of the day, it’s all a matter of understanding the context of the project. Knowing what you’ll be using the grinder for will help you determine the exact type and make that you should be looking for.

Variable Speed Angle Grinder
Sometimes a job just requires some low speed high precision cutting. Or maybe you need to gently file down some nails. In either case, you don’t want to speed up your grinder to full speed. Running at full speed will also drain the motor a lot quicker. As a result, you may have breakdowns a lot sooner than you expected.
When you spend the bit extra for a variable speed model, you will gain a lot more precision. You will also be able to set the speed for the job you are doing. At that means you will get much more accurate results.
Small Angle Grinder Uses
4.5-inch disc devices are the most common, but you can get models that are smaller. For most home DIY use this may not seem to make much sense. But they come in very handy for precision work. This would include hobby carpentry and even metal work, where you don’t want a hard to handle grinder.
Being able to switch to a small device and run at low revs will allow you to get extremely accurate cuts and sanding.
Electric Angle Grinder Motors
The motors on the smaller devices are significantly less powerful. You will still be able to use them for toucher materials like metal. But it will take a long time to get the job done. And because the motors are not design for that intense pressure they are more likely to fail. Try to stick to what you tool is designed for.
If you have multiple different uses then it may make perfect sense to have multiple machines to cover each job. Prices are very reasonable these days and all above products are available at great discount prices. Just check out the price check buttons above and don’t forget to review the customers’ comments while you are at it.
With so many good options to choose from, it can be quite a challenge to decide which one is the best for you. First consider your budget then narrow down your choices to what specs or make and model you are after. Don’ go for the most powerful model available if you just have some small project to work on. This will be very counterproductive and might mean it just ends up gathering dust.
